Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register for registering a product purchased by a customer at a retail store for settlement, and more particularly to a technique for confirming registration details.

[0002]

2. Description of the Related Art Recently, a thermal printer has been used as a cash register printer. Since the thermal printer is capable of high-speed printing, it does not print every time a product is registered, but after all products have been registered, the registration data is printed collectively and a receipt is issued.
By printing the registration data all at once, even if the operator purchases the same product multiple times even if the operator performs the registration operation for each product, the number of products is counted and the receipt details are displayed on the receipt details. Since the number of pieces and the total amount of money are printed for each, the receipt is easy to see and the paper is short.

[0003]

However, if the registration data is printed in a batch, even if the user wants to confirm the registration contents during registration, if the screen display cannot be used,
This causes a problem that confirmation cannot be performed easily. In particular, in a supermarket, there may be a two-person system in which a person in charge of registering goods in a cash register (checker) and a person in charge of handing over and cash transfer of goods (cashers) are busy. Since the system is operated by one person during the off-season, even if there is only one screen display, the registered contents can be confirmed by this screen display (see Japanese Patent Laid-Open No. 175974/1995).

Therefore, it is inevitable that the person in charge (casher section) who registers in the cash register does not have a screen display, and when it is desired to confirm whether or not the product has already been registered at the cash register, the settlement is completed. Then, there is a problem that you have to wait until the receipt is issued. In addition, providing a screen display on the cashier side has a problem of significantly increasing the cost.

The present invention solves the above-mentioned problems.
A first object is to provide an electronic cash register capable of confirming registration contents during registration without using a screen display even in an operation of printing registration data collectively. The second purpose is to provide an electronic cash register that allows the cashier staff to confirm the registered contents in the middle of registration without using the screen display, even in the case of a two-person operation on the cashier side and the checker side. It is in.

[0006]

The electronic cash register according to claim 1 stores the registration data of the registered merchandise in the storage means, calculates the total purchase amount, and receives the payment to settle. When a tightening operation is performed, an electronic cash register that issues a receipt in which the details are collectively printed based on the registration data stored in the storage means is operable and operated before the tightening operation. And a confirmation print key for printing the details of the registered product on the receipt paper based on the registration data stored in the storage means and issuing the confirmation statement , the scanner and the touch panel.
